Abstract

A találmány tárgya forgó érintkező karos áramkör megszakító és ezenmegszakítót tartalmazó szerelvény, amellyel a megszakító a terhelésrecsatlakoztatható. A megszakító az alábbi elemeket tartalmazza: - egypár egymással szemben elhelyezkedő kör alakú forgórész lemezt (17A,17B), és mindegyik forgórész lemez (17A, 17B) a kerülete mentén tartóhoronnyal (29) van ellátva; - egy mozgatható érintkező kar (15) van aforgórész lemezek (17A, 17B) között elhelyezve, és az érintkező kar(15) egyik végénél első mozgó érintkező (14A) van elhelyezve egy veleszemben elhelyezett álló érintkezővel (13A), míg az érintkező kar (15)másik végénél második mozgó érintkező (14B) van elhelyezve, amellyelszemben második álló érintkező (13B) van elhelyezve; - a megszakítóelrendezéshez tartozik egy forgókar (18), amely a forgórész lemezeken(17A, 17B) és a mozgatható érintkező karon (15) van átvezetve, ésezáltal van biztosítva, hogy a forgó érintkező lemezek (17A, 17B) és amozgatható érintkező kar (15) egymással összhangban forogjon el; - amegszakító tartalmaz még első érintkező rugókat (23A, 27B), ahol azelső érintkező rugók egyike (23A) a mozgatható érintkező kar (15)egyik oldalán van elhelyezve, míg a másik első érintkező rugó (23B) amozgatható érintkező kar (159 ellenkező oldalán van elhelyezve;továbbá - a forgórész lemezek (17A, 17B) egy U alakú emelővelösszekapcsolva vannak elhelyezve, ezen U alakú emelő (31A) egy pároldalsó kart tartalmaz, amelyek záró ívvel vannak egyik végükönösszekapcsolva, és a záró ív az érintkező karon (15) az állóérintkezőn kiképezett alakos felülettel kapcsolódóan van kialakítva,és ily módon konstans rugóerő van biztosítva az első és második állóérintkező és mozgó érintkező között. ÓThe subject of the invention is a circuit breaker with a rotating contact arm and an assembly containing this breaker, with which the breaker can be connected to the load. The circuit breaker includes the following elements: - a pair of circular rotor plates (17A, 17B) located opposite each other, and each rotor plate (17A, 17B) is equipped with a support groove (29) along its circumference; - a movable contact arm (15) is placed between rotor plates (17A, 17B), and at one end of the contact arm (15) a first movable contact (14A) is placed with a fixed contact (13A) placed opposite it, while the contact arm ( 15) a second moving contact (14B) is placed at the other end, opposite which a second stationary contact (13B) is placed; - the circuit-breaker arrangement includes a rotary arm (18) which is guided through the rotor plates (17A, 17B) and the movable contact arm (15), thereby ensuring that the rotating contact plates (17A, 17B) and the movable contact arm (15 ) rotate in harmony with each other; - the breaker also contains first contact springs (23A, 27B), where one of the first contact springs (23A) is placed on one side of the movable contact arm (15), while the other first contact spring (23B) is on the opposite side of the movable contact arm (159 placed; further - the rotor plates (17A, 17B) are placed in connection with a U-shaped lifter, this U-shaped lifter (31A) includes a pair of levers connected by a closing arc at one end, and the closing arc on the contact arm (15) on the stationary contact is formed in connection with a trained shaped surface, and in this way a constant spring force is ensured between the first and second stationary contact and moving contact.
